My 21 month is a long skinny boy - 34 in and 22 lbs. I am tempted to get him a medium, but I want to put a disposable under - should I go up a size?

Yes I would go up a size they fit snug. As they should !! You dont want things leaking out :)

I don't think you're going to fit ANYTHING under these! I ordered a size above what my son was at the time, and when I received it it was so tiny I don't think I could have gotten one leg in. I returned it so I'm not sure of the size but I ended up buying something else locally because I needed it ASAP. I do know that the intent for these it only to hold accidents in, not to absorb at all, so not sure there would be any room. Bottom line: these fit super small! I hope that helps...

there is no need for an additional disposable diaper if you use 2 of these reusable ones. but you might take the next lager size if you are planning to. my son was about the same size and height then yours and the medium still fits him.

My daughter is 51 inches and 55 pounds. Very skinny and always freezing. She is wearing a 6 and it works great. It is very tight but they are supposed to be tight though to work the best. She can't get it off herself once it is wet - I have to peel it off of her. I am considering moving her to an 8 because we have had this one for 2 years and it is finally getting worn out from chlorine. But I'm afraid the 8 might be too big. They really need between sizes. Personally at 48 inches I would go with the 6 because you really don't want "grow room" or bulk in a wetsuit.

Please...!! hepl me, my son is 9 years old, he is thin, what size would he be?

I'm a heavy-set 6'1" and I got the XL. They fit my waist fine, but are long on me. I think the L would probably have been better for me, so I think your son will do fine with the Med.

Hi christine. I am 6 2 and a muscular 216. The xl is perfect on me. U would probably be best served by a medium....but the size chart is fairly accurate. I suspect the l would be a bit billowy for you

Hi. I agree a small would work, but only if your son likes a very snug fit. A medium would work if he likes a little more room, but still snug. If in doubt have him try on one at your local sporting goods store. Oddly enough, my 17 year old softball player daughter who's 5'7" prefers a Large. It fits snug under her jerseys but allows for more movement so she's not choking.

Yes. Hey fit my twins, at 7lbs, and they still fit them now at 14lbs with lots of room to grow. They are bulky when babies are that little, though, and some clothes may not fit properly. We had to go up a size on pants and jumpers because of the bulk. They worked, though, with fewer blow-outs than disposables.

Hi, hope it isn't too late but you should get the medium. I am 5'6.5", 27 weeks and 162lbs. The small fits me perfectly on the next to the largest setting. You can adjust the medium to one of the smaller settings.

I think it should fit him at his current size, although it might not fit him for very much longer. My 7 month old was about that size last month when he stopped wearing it (not because it didn't fit anymore, just because we thought it was time). The makers of the suit made the crotch really low to allow for taller/longer torso babies, so his arms and legs might stick out more than they would for other babies, but it won't be uncomfortable for him. My little one is pretty chunky, and we never had an issue with tightness around belly or anything. Hope this helps!

I would recommend sizing up because these run small. My 2 year old is 39 inches tall and 33 pounds, and I got the Small which says it is supposed to fit a 4yo. It fits him perfectly over shorts and a t-shirt. The legs are a little long but rolling them up works fine.

You definitely want it tighter than loose so the baby fits snugly. I'm not sure what size would be best for you. I'm 5'9" and wear a size 14 or XL in shirts/dresses and the large was too big and didn't shrink in multiple hot water washes. I did have the organic version so I don't know if that matters with the size (I don't think it should). Maybe if you call the company they would help more. Sorry I couldn't be more helpful.

Hi Derrick, My impression is that the size run small. My son is 2 years and 4 months (he is not tall but not skinny either) and I had to change the 2T for 3T and it just fine right. For my son that is 4, who is smaller for his age and very skinny the 4T fit just right but I have the feeling i may need to change them soon!!. I hope this was helpful.

I got the 16 for my 7 year old, she's very small for her age and has already outgrown it. I would recommend a size up.

You could probably get the medium and have no problems I got a small for my min pin he's 16 pounds and the devise is at the smallest setting. It gets a lot bigger.

XL will be too big. Large may even be big. My daughter is 12 mo and 18 lbs (small peanut) and still wears a medium with plenty of room. I understand you not wanting to purchase another in a couple months, but you don't want TOO much wiggle room either. Maybe you could purchase a large just to see, but keep in mind he/she may not be able to wear it yet and you may have to get a medium?

My daughter is 21 months, weighs 21 lbs and wears mostly 12-18 month clothes and I bought her a large. It fit snugly around her thighs. I hope that helps!

Both of my boys are thin. My 8yr old wears a 7/8 slim. I got him the small and we pull the shoulders tight and it works. My 9 these old wears an 8/10 and wears the med comfortably.
